RFID leh NFC inzawmna leh danglamna .

Internet of Things hi a bik takin technology pawimawh pathum a awm a, chungte chu connection, identification, leh data operation te an ni. Thil hriat theihna hi Internet of Things kalpui dan hmasa ber a ni a, chu chu thil pakhat zel chu a danglam bik taka hriat leh thliar hran a ni.

RFID-in a entîr object identification technology chu Internet of Things nen a inmil deuh ṭhin a, tunah chuan RFID, NFC-a evolution technology chu field hrang hrangah hmun pawimawh tak a chang a ni. He thuziak hian IoT device-te identification technology leh RFID leh NFC inzawmna chungchang a sawi a.

RFID a ni a.
Contactless Radio Frequency Identification (RFID) hi a bul berah chuan wireless communication technology a ni a, wireless electromagnetic wave hmangin data a thawn chhuak thin a ni. Mahse, RFID hi general communication technology aiin a danglamna chu a tum ber a ni a, phone call emaw text message thawn emaw a ni lo. RFID hi a bul berah chuan thil nena inzawm tag te hriatchhuah leh track nan hman a ni a, chu chuan object management a ti thei a ni.
RFID technology hi warehousing leh logistics-ah hman a ni nasa hle a, chu chu thil zawn chhuahna atan hman a ni.
RFID system hian tag hmangin thil a hriat theih a. Tag bakah hian RFID system te hian bidirectional wireless transceiver an nei bawk a, chu chu interrogator/reader an ti a, chu chuan tags ah signal a thawn a, an feedback pawh a chhiar tel bawk.

RFID system ah hian reader leh tag 1000 a awm a.
RFID hi passive RFID leh active RFID ah then a ni. Passive RFID tih hian a tlangpuiin passive RFID without battery a kawk a, chu chu circuit chu hnathawhna hmuna khalh turin electromagnetic wave dawngtuah a innghat vek a, tag-a recognizable distance chu a danglam lo. Active RFID system hian a tlangpuiin active RFID tags a kawk a, battery level a tlahniam chuan a hriat theih distance a tlahniam ang.
ETC system RFID technology hmanga kal chuan passage a awlsam zawk .
Active RFID hian a tlangpuiin recognition distance a nei a, chu chu highway toll booth leh automatic parking lots te tan ETC system te a ni a, a tlangpuiin 2.4GHz-a thawk active RFID an hmang thin. Mahse, ETC tag ah hian battery a awm. Battery battery a tlakchham chuan a thawh theih nan thlak a ngai a ni.

RFID tags 1000 a ni.
RFID tag hi hmun hnih a awm a, chungte chu integrated circuit (IC) leh antenna te an ni:
IC hi data dahkhawm leh process nan hman a ni a, RF signal te chu modulate leh demodulate nan hman a ni a, chubakah chhiartute’n anmahni hnathawh an khalh theih nan signal an tihchhuah atanga energy an lakkhawm a ngai bawk.
Antenna hnathawh chu wireless signal thawn chhuah leh dawn a ni.
EPC code format hian zawi zawiin UPC code hlui chu a thlak thei a, chu chu product barcode a ni.

RFID tag-a data dahkhawmna .
RFID tag-a data format dah chu a tlangpuiin EPC (Electronic Product Code) code a ni. EPC code hian khawvela thil awm zawng zawng a hre thei vek a ni. EPC Codes structure hi EPCGLOBAL TAG TAG DATA Standard hmanga siam a ni a, hei hi publicly available standard a ni a, EPCGLOBAL INC website atang hian a thlawnin download theih a ni.

NFC technology hmanga siam a ni.
Tunah hian Near Field Communication (NFC) hi mobile phone hmanga inbiakpawhna interface hman tlanglawn tak a ni. Smart device te hian an inhnaih tawn a, data an inthleng thei a ni. NFC device te hian RFID ang bawkin passive NFC tag hmangin an inbiak theih bawk.

NFC inbiakpawhna hmanrua .
NFC technology hi RFID technology atanga lo piang chhuak a ni a, communication protocol bakah hian NFC standard pawh hian data exchange format a tarlang bawk. Induction card reader, induction card, leh point- to-Point functionality te chu NFC chip pakhatah a inzawm khawm a, a hlat deuh deuhnaah device inmil tak tak hmangin data a hre thei a, a inthleng thei bawk.

NFC leh RFID inthlauhna .

Hnathawh Frequency Band .
NFC hi RFID technology subset anga hriatthiam theih a ni a, 13.56MHz frequency band hmangin, RFID hian frequency band dang a keng tel bawk.
RFID tan hian working frequency band tam tak a awm a, chung zingah chuan low frequency band-ah 125KHz, high frequency band-ah 13.56MHz, ultra-high frequency band-ah 433.92MHz leh 915MHz te, microwave frequency band-ah 2.45GHz te an tel.

Inbiakpawhna hlat zawng .
NFC hi near-field communication tia hriat a ni a, inbiakpawhna hlat zawng pawh a hnai hle tak zet a, 0.1m aia tam a ni lo.
RFID chi hrang hrang a awm a, a hriat theih distance pawh a inang lo. RFID access card ang bawkin recognition distance pawh NFC nen a inang tlangpui. Mahse ETC application scenario atan chuan recognition distance rei tak a mamawh a ni. Long-distance RFID hian recognition distance a nei a, meter sawm emaw, meter za emaw pawh a thleng thei.

Application scenario hrang hrang .
RFID hi active emaw passive emaw pawh nise, object recognition atan hman a ni ber. Logistics, transportation, leh warehousing zawng zawng hi RFID technology hmanga thil zawrh chhuahna atana hman vek a ni.
NFC chip inzawmkhawmna hi a sang zawk a, card reader leh tag te inzawmkhawmna pawh a tel. Hei bakah hian NFC-a bidirectional communication capability pawh tihchak a ni bawk. Chu chu NFC hi hriat hlawhna atana tag atan chauh ni lovin, data exchange atana bidirectional communication method atan pawh hman theih a ni tihna a ni. Tunah hian NFC hi payment field-ah hman tam ber a ni.

NFC technology hi payment scenario-ah hman a ni nasa hle a ni .
A pum puiin NFC hi RFID technology hmanga siam ni mah se, application scenario hrang hrangah substitutive effect a nei lo. Chubakah, tunlai hian RFID hmanna tur application scenario tam tak a la awm a, NFC hian tun dinhmunah chuan an match thei lo.
Payment leh close range object recognition field-ah pawh QR code hian scenario tam takah NFC role a play thei a ni. Tunah hian NFC hi smartphone-te tana inbiakpawhna interface mamawh tak a ni lo.
